Java is statically typed so you can’t point a variable to an instantiated object without declaring the class.
You can create classes without a pointer but they will just be collected by the garbage collection machine unless you’re passing them to something that uses the new object you’re creating.
This is nothing in Java:
myObject = {“x”:5,”y”:10,”z”:12,”name”:”something”}
Java doesn’t know what to do with it.
